I'm not active in the wiki matters anymore, but I was contacted for this, so...
As Kiri said, for the Old Tiering system it was enough.
Case in point, as long as one could prove that the dimensions were spatio-temporal ones, they were considered enough to warrant the higher tier by default. I'm not all that keen on the new tiering system but from what little I read of it, I'm pretty certain the requirements for those things have been raised enough that she does not qualify anymore.
That said, even back when it did I personally vouched that such should scale only to Beatrice's hax. That is the reason why even prior to this thread she is rated 5-A so... Uh.
I don't really see how much even changes there other than handwaving the hax in thread?
Or does this reduce her range also and whatever?
